JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 560,565, dated May 19, 1896.

Application filed July 15,1895. $erial No. 556,026. (No model.)

To aZZ whom it may concern:

Be it known that I,WILL1AM G. BncKwrrrr, a citizen of the United States, residing at Pratt-ville, in the county of Autauga and State of Alabama, have invented certain new and useful Improvements in J ournal-Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. r

This invention contemplates certain new and useful improvements in journal-boxes, and relates more particularly to that class known as oscillating.

The object of the invention is to provide a device of this character which will be simple in construction and efficient in operation, one which may be easily set up or taken down, and one in which simple and efficient means are provided for lubricating the shaft supported by said j ournal-box.

In carrying out my invention I form a bed or base plate of two parts or sections, each of which is provided with a bearing for the reception of trunnions extending transversely from the journalbox or bearing proper. This latter is also composed of two parts or sections, which form an interior chamber, in which is designed to fit a sleeve or lining of any suitable antifrictional metal. This sleeve is also preferably formed in two parts or sections, and the upper section is provided with grooves in its top surface and a lug or projection extending up into an oil-reservoir formed in the upper section of the journalbox. The oil-reservoir is provided with suitable outlet holes or openings, which register with grooves or recesses formed in said interior chamber and leading to the bottom thereof, where a supplemental reservoir is formed. The lower section of the antifrictional sleeve is provided with a longitudinal slot, in which fits a strip of wool or felt or other similar substance, which will convey lubricant by capillary attraction from said supplemental oil-reservoir to the shaft supported by said j ournal-boX.

The invention will be hereinafter more fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation. Fig. 2 is a crosssectional view on the line 09 :10, Fig. 1. Fig. 3 is a plan view with the top sections removed. Fig. 4c is a bottom plan view of the top section of the journal-box. Fig. 5 is a detail view; and Fig. 6 is a sectional detail view on line y y, Fig. 1, the base-plate being removed.

Referring to the drawings, A designates the bed or base plate, which is formed in two parts or sections a a, which are designed to be united together at a by means of suitable screws or bolts, said sections being provided with holes or openings a for the accommodation of securing-bolts (not shown) used in mounting said bed or base plate into position.

The journal box or bearing proper is formed in two parts or sections 29 b, united together by nutted bolts 6 the heads of which fit in suitable grooves or recesses in bed or base plate A and corresponding recesses in the section Z). From the lower section 1) project transverse trunnions 17 which are pivotally supported in bearings 1), extending upwardly, one from each of the parts or sections a co of said bed or base plate. The interior of the sections 1) and b' is hollowed out to form a cylindrical chamber 19 having end walls 6, said chamber being designed to accommodate a bearing-sleeve 0, formed in two parts or sections 0' O of semicircular form in crosssection. This sleeve is made from any suitable antifrictional metal, preferablyBabbitt metal.

D is an oil-reservoir located in the upper portion of section b of the journal-box, feed holes or openings cl and d being formed in the bottom of said reservoir. The opening d registers with a groove or recess (1 in the inner surface of the section b, which groove in turn registers with a similar groove (1 in section b, which with a groove CV in section 0 forms a conduit for the oil. The opening cl registers with a groove (1 in the top surface of the section 0 of the antifrictional sleeve, and this groove in turn registers with a second groove 61 in section b, communicating with a groove 01 of section I). (See Fig. 6.) The grooves 61 and cl are connected by a groove (Z forming a supplemental oilreservoir, in which is designed to rest a strip of wool or felt (Z which is projected through a slot (1 of the section 0 of sleeve C. By means of this piece of wool or felt a gradual feed of oil to the shaft X is maintained by capillary attraction. Vhile I have specified wool or felt for this purpose, I do not limit myself thereto, as any suitable fibrous substance may be employed without departing from the spirit of my invention.

The section 0 of sleeve 0 is provided with a lug or projection c, 'which extends through a hole or opening (2' of section 1) into the oilreservoir D, the section of said sleeve being thereby prevented from revolving with the shaft X, mounted in said sleeve. The section 0 is provided with a lug e fittingin a recess 6 of the section Z). The amount of longitudinal play of shaft X in its bearings is regulated by an ad justin g-screw E, mounted in a cylindrical portion a of the section I). (See Figs. 1 and 3.) The oil-reservoir D is provided with a suitable cover 6 pivoted at e to lugs c of the reservoir.

The advantages of my invention are apparent to those skilled in the art to which it appertains, audit will be readily seen that because of the bed or base plate being formed in two parts or sections the same may be easily mounted, and its accurate Working and ease of adjustment will be thereby insured. It will also be seen that the piece of wool or felt will effect a gradual and efficient lubrication and at the same time prevent any grit or foreign substance from reaching the interior or bearing-surface. It is clear also that the antifrictional sleeve 0 may be easily replaced when worn.

I claim as my invention- 1.
